For those of you determined to make your own custom lines, this brake line tubing is specially made with seamless walls and is the correct raw stock for a custom brake line job. The handheld tubing bender will be handy for making the lines conform to the required contours of the installation. Measure and cut all lines with a little extra length to allow for the flaring process at the ends. Don't forget to install the fittings onto the tubing before creating the flare. This 20-foot coil of brake line is from Inline Tube. This line is OE steel and costs $25. Stainless steel costs extra at $59.
